When you offer risk reversal in your offer you make it easier for the customer to get to know you, like you, and trust you which means the barrier to entry is much lower.
But there is one important thing not to forget to make sure the risk reversal is appropriate to the product or service you are providing so that the client sees it as something of value rather than a throwaway bolt-on.
With some products or services getting your money back is the last of your worries if it fails so you then need to go one step further the classic 'if I don't deliver what I promise I won't charge you' doesn't really put the customer at ease because they will still perceive they are the ones taking the risk.
In this case, you need to ensure as well as having a good risk reversal policy you also have testimonials and reviews.
The reason is when you can demonstrate that you can provide the product or service you promise and that you have happy satisfied clients they will feel that if it can work for you it can work for me.
There's a real difference between "satisfaction guaranteed" and spelling out the details of your risk reversal.
Make it really part of your offer, and educate your clients on what you're doing for them, and what you will do to make it worth their while, and what you'll do if they don't believe it's worth their while.
Use language that paints a picture of your client's situation in the future so say something like "𝘪𝘧 𝘺𝘰𝘶 𝘥𝘰𝘯'𝘵 𝘨𝘦𝘵 𝘵𝘩𝘦𝘴𝘦 𝘳𝘦𝘴𝘶𝘭𝘵𝘴, 𝘵𝘩𝘦𝘯 𝘐 𝘥𝘰𝘯'𝘵 𝘸𝘢𝘯𝘵 𝘰𝘳 𝘥𝘦𝘴𝘦𝘳𝘷𝘦 𝘺𝘰𝘶𝘳 𝘮𝘰𝘯𝘦𝘺 𝘢𝘯𝘥 𝘐'𝘭𝘭 𝘣𝘦 𝘩𝘢𝘱𝘱𝘺 𝘵𝘰 𝘳𝘦𝘧𝘶𝘯𝘥 𝘪𝘵 𝘣𝘢𝘤𝘬 𝘵𝘰 𝘺𝘰𝘶"
